lMPROVEMENT lN,CON\ /ERT|NG ROTARY INTO RECIPROCATING MOTION- Speeification Forming part of Letters Patent No. 48,502, dated July 4, 1865.

tion thereof, reference being had to the accompanying drawings, making a part of this speci fication. A

Figure 1 is a side view. Fig.2 is an end view, and Fig. 3 is a view representing the motion of the rock-shaft as operated by the inclined-plane wheel.

The object of my invention is -to overcome the dead-points in ordinary crank movements, which I have done so completely that my machine is nearly as easily started from any point of the inclined'plane wheel as another, and so perfect and easy is the movement that much friction is avoided and no jerking or noise is produced by its operation.

To enable others-skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Similar letters indicate like parts of all the figures.

A is the rock-shaft, constructed strongly of metal, with anti-friction roller-supporters constructed at opposite points thereon transverse to the points of suspension, and with suspensioirarms O G hung on pivots bb, attached to the arms and bearing insup'ports in the frame, as represented. y

Bis the inclined-plane wheel, of metal, strong enough to retain its true form and its disk wide enough to make an inclined way for the anti-friction rollers. This inclined-plane wheel is attached to the fly-wheel by supporters sufiicient in number, strength, and length to give the wheel its properinclination andmaintain it.

0 is the fly-wheel, of ordinary construction.

D is the shaft, made in the ordinary way, to which the tly-wheel and its inclined-planewheel are attached.

E is an ordinary driving-wheel, which, with its belt 01 passing arounda pulleyion the shaft, indicates one of the common modes of the application of rotary motion.

a a are anti-friction rollers, operating between the rock-shaft A and theinclined-plane wheel B, turning on pivots resting on each endof the rock-shaft.

The operation of the machine may be thus described: Power being applied to the shaft D, the d y-wheel and its attached inclined-plane wheel are setin motion. Against thisinclinedplane wheel the anti-friction roller at each end of the rock-shaftruns, and, as the inclined-plane wheel moves the reciprocating motion is-imparted noiselessly, easily, and without deadpoints to the rock-shaft, from either end of which it may be communicated by any of the ordinary and well-known forms to the saw of a saw-mill, to a sewing or any other machine.

What I claim as my inventiomand desire to secure by Letters Patent, is-

The combination and arrangement of rockshaft A, the inclined-plane whee'l B, the flywheel 0, shaft D, and anti-friction rollers a a,

constructed, arranged, and operating as and -for the purpose herein described and set forth.
